3.3 Estimation Strategy
3.3.3 Financing Educational Expenses
La temperatura preferida encontrada en este trabajo para los adultos de L.
vannamei fue de 26 °C independientemente del método utilizado, es probable que
tanto su temperatura preferida como la modificación de sus parámetros metabólicos, estén determinados por la reproducción, esto para evitar daño a los espermatozoides, ya que la temperatura en la que los espermatozoides tienen una mejor movilidad es de 26 °C al igual que la temperatura preferida reportada en este trabajo.
Las variables más sensibles para determinar la termotolerancia del camarón blanco son: La glucosa, que incrementó 3 veces el valor basal en tan solo 10 minutos después de someter a los camarones a estrés térmico. La actividad de la fenoloxidasa se activo rápidamente como respuesta a estrés agudo para amortiguar el efecto del estresor.
Considerando que la presión osmótica de la hemolinfa es la responsable de mantener la homeostásis en el organismo y que no se observaron diferencias significativas entre los organismos sometidos a su temperatura crítica máxima independientemente de la temperatura de aclimatación en la que se encontraban obteniendo valores máximos de 809 mmol kg-1 en la presión osmótica de la
hemolinfa, se infiere que valores de osmolaridad por encima de este causarán la muerte del organismo probablemente por un desajuste en la concentración de agua y iones a nivel celular.
Según resultados preliminares en la expresión diferencial, se observó la expresión de algunas bandas y la ausencia de otras al comparar condiciones basales con condiciones de estrés. Por lo que es factible detectar estos cambios a nivel genético.
La determinación de parámetros fisiológicos como la preferencia térmica y la tasa metabólica de organismos de alto valor comercial como el camarón blanco es de suma importancia para poder establecer sitios adecuados para reproducción y cultivo que permitan una correcta utilización del recurso.
